JAMES RAPHAEL BOSSETTER, 0F KNOXVILLE, TENNESSEE, ASSIGNOR TO THE WM. J. OLIVER MANUFACTURING COMPANY, OF KNOXVZLLE, TENNESSEE, A CORPORATION OF TENNESSEE.

PLOVI.

To all whom it may concern:

Be it known that I, JAMEs RAPHAEL Ros sE'rTER, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to improve the construction of a moldboard plow by increasing its strength and more perfectly securing its parts togetherso as to hold the original shape and relation of the parts necessary for a perfectly operating implement; and also to simplify the construction of a plow having its working parts fitted and detachably fastened to a frog or standard.

The invention will hereinafter be first fully described with reference to the accompanying drawings, which form a part of this specification, and then more particularly pointed out in the appended claims.

In said drawings: Figure 1 is a side elevation of a plow embodying my invention as seen from the moldboard side. Fig. 2 is a side elevation looking at the landside side. Figs. 3 and 4 show reverse and obverse sides of the plowpoint. Figs. 5 and 6 are similar views of the frog or standard constituting a frog to which the working parts are fastened. Figs. 7 and 8 are obverse and reverse views of the landside. Fig. 9 is a detail. Fig. 10 is a plan view of the landside looking down upon itsupper edge.

As will be observed from the drawings, the implement in which I have incorporated my improvements for the purpose of illustration herein is modeled after the general design and construction of the plow shown in my former patents No. 64 L099 of February 27, 1900 and No. 740,373 of September 29, 1903, somewhat modified, though it should be understood that I do not confine myself to any particular construction but reserve the right to any and all embodiments of which my said improvements are susceptible.

The parts of the plow are designated in the drawings as follows:

Specification of Letters Patent.

Application filed. May '7, 1909.

Serial No. 494,529.

1 is the beam; 2 is the frog or standard attached to the beam and having the working parts fastened thereon; 3 is the point; 4: is the moldboard; 5 is the landside.

The frog 2 is of the general form of the plow, having an oblique, sloping and concaved side 6 which provides the seat or foundation for the plowpoint and forward portion of the moldboard, and having a flat landside side forming the front solid part 7 of the landside which terminates at an approximate point, and provided with a recess 8 in which fits the detachable landside proper 5. merge into a sloping line at the front, making a comparatively heavy solid casting at the front and toe of the frog, and the sloping side 6 is joined to the recessed base portion of the landside side by a web 9, making a very firm, solid and strong foundation. The landside face is cut preferably at about four inches from the point to provide the recess 8 for the landside.

For convenience, the bolts and bolt holes for fastening the working parts to the frog are indicated as follows: 10 is applied to the bolt and holes for the point; 11 and 12 indicate the two bolts and holes for the moldboard; l3 and 1 1 the two bolts and holes for the landside. The other holes appearing in the moldboard and landside are of course for attachment of the plow-ham dles. The beam 1 is or may be bolted to the frog at 15 and at 13 by the same bolt which secures the landside, and also by a blind bolt at 16 to hold the foot of the beam when the landside is removed for any cause. By the features of my invention now to be described, the parts are effectively secured or interlocked together so that the point and landside, even if their fastening bolts should work loose, will be held firmly in place upon the frog, maintaining the original shape and curvature of the plow and particularly its suck or dip as well as the inward curvature of the landside face which gives the gather that is necessary to make a plow run well during its life. The frog 2 provides a solid foundation for the plowpoint 3, which is preferably of the form substantially as shown, having an upwardly extending cutting blade or colter 17 and a lat- Patented Feb. 15, 1910.

The sides 6 and 7 of the frog eral rearwardly extending wing 18 to fit upon the sloping side of the frog below the lower edge of the moldboard. On the under or reverse side of the plowpoint, behind the front cutting edge of its colter and extending to practically the point proper or toe of the plowpoint, is an elongated notch 19 in which fits the front edge and toe of the frog, it being observed that substantially the whole plowpoint is thus seated upon its foundation, reducing strains tending to tilt over the plowpoint at the top; and the upper end of the colter or part 17 is provided with a beveled lug 20 which fits under the upper front corner of the moldboard in a recess or under a corresponding bevel 21 therefor in the edge of the moldboard, obviating any tendency toward outward displacement at that place and holding the upper part of the plowpoint firmly to its seat; while another lug 22 at the upper edge of the wing 18 engages under the lower edge of the sloping side 6 of the frog at the point 23, preventing outward displacement; and thus the plowpoint as a whole is always maintained fast in its proper position with its surfaces flush with the moldboard, keeping the original curvature and preventing the plow from losing its desired suck or dip On the landside is incorporated a feature that is the subject matter of my United States Letters Patent No. 925,134t, granted June 15, 1909; that is a beveled recess 24L on the front end of the landside 5 which receives and fits under a correspondingly shaped lug 25 on the front wall of the recess 8; the purpose of which, as more fully explained in my aforesaid application, is to hold the front end of the landside from outward lateral dis placement and thereby maintain the inward curvature or gather of the landside face of the plow necessary to hold the implement to a straight line while at work and preventit zigzagging in the furrow and running out of the land; and in conjunction with this interlocking connection at the front end of the landside there is another lug or rather a curved finger 26 at about the middle of the landside and on its inner or reverse face, which lug or finger 26 hooks or looks over the rear edge of the side 7 or web 9 of the frog at the point 27 and firmly attaches the landside at that point, as well as in front, making a very rigid landside from the fact that outward strain is overcome by said lug 26. The front end of the landside 5 and front wall of the recess 8 are preferably straight, which is of course thesimplest way of making them, but are preferably forwardly inclined which arrangement assists in giving rigidity to the landside and in conjunction with the interlocking connections at 25 and 27 practically relieves the bolts from shearing.

It will be observed that I thus provide a very practical and efficient implement, having its parts so effectively secured together as to prevent outward displacement in event of loosening of the fastening bolts and therebyrpreserving the original shape of the plow and the correct curvature of its surfaces.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a plow, the combination of the pl0wpoint provided with a colter or cutting portion extending upwardly along the front edge of the moldboard, said colter portion having a lug on its upper part, and the moldboard under the edge of which said lug is fitted and secured, to prevent the point from straining outward at the top.

2. In a plow, the combination with the frog and moldboard and plowpoint fastened thereupon, of lugs on the plowpoint one of which engages under the edge of the moldboard and another of which engages under the edge of the frog.

3. The combination with the frog and a detachable moldboard, of the detachable plowpoint formed with a colter or upwardlyextending cutting portion which is provided on its rear edge with, a lug engaging under the adjacent edge of the moldboard and between the moldboard and frog, substantially as and for the purpose described.

4. In a plow, the combination with thefrog having a recess for a detachable landside, of the landside fitted therein, an interlocking connection between the front end of the landside and front wall of said recess to prevent lateral displacement of the front end of the landside outwardly, and a lug on the rear side of the landside engaging with the frog to hold the rear portion of the landside against lateral displacement.

In a plow, the combination with thefrog having a recess for a detachable landside, of the landside fitted therein and bolted to the frog, and interlocking connections between the front end of the landside and front wall of said recess and between the rear of the landside and the frog, for the purposes set forth.

6. A plow, consisting of a frog of the general form of the implement, having a flat landside face terminating in an approximate point and having an oblique sloping side, a moldboard and point fitted upon and detachably fastened to said sloping side, the point formed with an upwardly-extending cutting part and with a lateral wing, the frog providing a solid foundation for nearly the whole under side of the point which is seated upon the frog adjacent to the front and lower edges of the moldboard, and the flat side of the frog having a recess fora landside which extends near the front edge of the frog, and a landside fitted on said I and means for fastening the plowpoint to recess and detachably bolted to the frog. the frog. 10 7.
